wisdom of the Perl Monks concerning the following question:

Hi all,
Has anyone done much work with gnuplot? I am trying to generate image maps from png/gif images generated from gnuplot. As far as I can tell, what seems to be holding me up is finding out the values (in pixels) of lmargin, rmargin, tmargin and bmargin. If I knew these I could calculate the positions of the points on my graph.
I am currently awaiting answers from their mailing list but I thought I'd ask here as well. The interface I am using to gnuplot is Chart::Graph::Gnuplot. Thanks in advance.

Hi,
I am not sure if the values there are in pixels or characters. For what I am trying to do I would prefer to work in pixels. If I run the gnuplot command "show margins" I just get a message stating that they are computed automatically. I would like to get these computed values in pixels ... or am I asking too much?
